57) neglecting terms independent of elastic displacements and noting that eTDeT = 6jD6, and so forth. 57) may finally be written in terms of element nodal displacements by using Eq. 65) may also be derived by using the principle of virtual work for dynamic systems, also known as Hamilton's principle, first at element level and then analyzing the same for the entire structure. Most structures are characterized by the presence of structural as well as viscous damping, in which case Eq. 66) in which CD is viscous damping and equals aK -j- f$M, if the damping is proportional.

2. 1 2), i takes the values 1 , 2, or 3 depending on whether the problem domain is in one- , two- , or three-dimensional space. The notation ^/,/ implies differentiation with respect to the i independent variable, and a repeated index, unless noted otherwise, means a summation over the range of the variable dimension. The term H[ is the component of the surface normal vector. Purchased from American Institute of Aeronautics and Astronautics DISCRETIZATION OF PHYSICAL SYSTEMS n xA 19 n xB Fig. 1 Line element A-B.

2 Argyris The series of papers under the title Energy Theorems and Structural Analysis by Argyris5 is perhaps one of the most significant landmarks in structural mechanics of all time. This publication completely developed the matrix theory of structures for the discrete elements and then went on to show that this is only a particular case of the general continuum in which stresses and strains have been specified. This breakthrough led to the concept of flexibility and stiffness (as given by Argyris).
